Security for industrial automation and control systems-Technical security requirements for IACS components 工业自动化和控制系统的安全性

发布日期： 2019-05-07

范围:IEC 62443的本部分提供了与IEC TS 62443-1-1中描述的七项基本要求（FRs）相关的详细技术控制系统组件要求（CRs），包括定义控制系统能力安全等级及其组件SL-C（组件）的要求。
根据IEC TS 62443-1-1的定义，共有七项基本要求（FRs）:a）识别和认证控制（IAC）、b）使用控制（UC）、c）系统完整性（SI）、d）数据保密性（DC）、e）受限数据流（RDF）、f）事件及时响应（TRE）和g）资源可用性（RA）。
这七个FRS是定义控制系统安全能力级别的基础。与SL-T或已实现的SL（SL-A）相比，定义控制系统组件的安全能力级别是本文件的目标和目的，这超出了范围。
注1:参考IEC 62443-2-1[1]了解一组等效的非技术性、与程序相关的能力
完全实现SL-T（控制系统）所需的要求。

Scope: This part of IEC 62443 provides detailed technical control system component requirements (CRs) associated with the seven foundational requirements (FRs) described in IEC TS 62443-1-1 including defining the requirements for control system capability security levels and their components, SL-C (component).
As defined in IEC TS 62443-1-1 there are a total of seven foundational requirements (FRs):a) identification and authentication control (IAC),b) use control (UC),c) system integrity (SI),d) data confidentiality (DC),e) restricted data flow (RDF),f) timely response to events (TRE), andg) resource availability (RA).
These seven FRs are the foundation for defining control system security capability levels. Defining security capability levels for the control system component is the goal and objective of this document as opposed to SL-T or achieved SLs (SL-A), which are out of scope.
NOTE 1 Refer to IEC 62443-2-1 [1] for an equivalent set of non-technical, program-related, capability
requirements necessary for fully achieving a SL-T(control system).
